GREASING AND OILING DEVICE.

Application filed January 11, 1924. Serial No. 685,670.

To all ill/(01ft it may concern:

Be it known that I. SAM SPARROW RUN- DELL, a citizen of the United States, residing at Bogalusa. in the parish of Washington and State of Louisiana, have invented a new and useful Greasing and Oiling Device, of which the following is a specification.

This invention aims to provide novel means whereby a heavy grease, or a liquid grease may be applied to a part which is to be lubricated.

It is within the province of the disclosure to improve generally and to enhance the utility of device-s of that type to which the invention appertains.

lVith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, wit-hin the scope of what is claimed, changes in the precise embodiment of the invention shown. can be made, without departing from the spirit of the invention.

In the drawings:

Figure 1 shows in longitudinal section. a device constructed in accordance with the invention; Figure 2 is a cross section on the line 2-2 of Figure 1.

A person interested in a device of the general sort shown in this application should refer to my Patent No. 1,518,675, issued on December 9, 192 1, and covering sundry improvements in an oil cup.

In carrying out the invention, there is provided a support 1 which may be a por tion of the mechanism to be lubricated, the support being supplied with an opening 2. A tubular casing 3 is secured at 4 to the support 1, about the opening 2. Vithin the casing 3 is disposed a tubular sleeve 5 provided with a circumferential spacing rib 6, which, cooperating with the casing 3, holds the sleeve 5 apart from the casing. lhe numeral 7 designates a cap provided at one end with a reduced flange 8 threaded at 9 into the casing 3. Since the sleeve 5 is provided with the rib 6, the sleeve is held centralized with respect to the casing 3 and the flange 8 on the cap 7 may be introduced without difliculty between the parts 3 and 5. The cap '7 is provided with a chamber 10 which receives the upper end of the sleeve and when the flange 8 of the cap 7 is threaded into the end of the casing 3the removable sleeve 5 is bound between the cap 7 and the member 1. The cap 7 has an axial bore 11 communicating with the sleeve 5.

A tube 12 is removably mounted in the bore 11 and has a tapered end 14 received in the opening 2 of the support 1, without filling the opening completely. The tube 12 has a head or shoulder 15, which, bearing against the outer end of the cap 7, holds the tube 12 in such a position that the tapered end 14 of the tube is received properly in the opening 2 of the support 1. On the tube 12, a follower 16, in the form of a disk, is mounted for reciprocation, the follower fitting closely but slidably in the sleeve 5. A c01npression spring 17 surrounds a portion of the tube 12, one end of the spring abutting against the follower 16, and the other end of the spring abutting against the cap 17.

In practical operation, the follower 16, responding to the action of the spring 17, will force the heavy grease in the sleeve 5 through the opening 2. Liquid grease may also be introduced by way of the tube 12.

The tube 12 exercises a four-fold office; first, it constitutes a means whereby liquid grease may be introduced into the opening second, it acts as a guide for .the follower 16; third, it serves to hold the spring 17 in place; and fourth, it prevents the heavy grease from being advanced too rapidly through the opening 2 responsive to the advancement of the follower 16, it being observed in this connection, that the tapered end 14 of the tube 12 extends into the opening 2.

Practically, the member 1 forms a closure for one end of the casing 3.

The sleeve 5 is not removable with the cap 7, unless those parts happen to be stuck together. In practice, a number of sleeves 5, charged with grease, may be kept on hand, and when one sleeve is empty, a full sleeve may be slipped into casing 3, the cap 7 then being mounted in place, as hereinbefore explained.

I claim:

1. In a device of the class described, a casing provided in one end with an opening, a cap removably mounted on the other end of the casing, a sleeve within the casing and engaged with the first specified end of the casing, and with the cap, a tube carried by the cap and discharging into the opening, a follower slidable in the sleeve and on the tube, and a compression spring surrounding a portion of the tube, one end of the spring abutting against the follower and the other end of the spring abutting against the cap.

2. In a device of the class described, a casing provided in one end with an opening, a sleeve within the casing and engaged with said end of the casing, a cap engaging the casing detachably, and engaging the sleeve, the sleeve having the rib which cooperates with the casing to space the sleeve from the casing for the reception of the cap between the sleeve and the casing, a tube carried by the cap and discharging into the opening, a follower slidable in the sleeve and on the tube, and a compression spring surrounding the tube and interposed between the cap and the follower.

3. In a device of the class described, a

casing provided at one end with an open- 2 ing, a cap reinovably mounted on the other end of the casing, a sleeve within the casing and engaged with the first specified end of the casing and with the cap, a tube mounted in the cap and having a bore including a tapered portion, the tube being provided with a tapered end wherein said portion of tl e boreis locat-etl, the tapered end being received in the opening, the tapered end of the tube filling the opening partially, the tube having a shoulder which engages the cap to limit the introduction of the tapered end of the tube into the opening, a follower slidable in the sleeve and on the tube, and a spring surrounding the tube, one end of the spring abutting against the follower, and the other end of the spring abutting against the cap.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature.

SAM SPARROW RUNDELL.
